CAN-SOLDERI'NG MACHINE.

SPECIFICATION formingpart of Letters Patent No. 278,100, dated May 22,1883,

i Application filed February 28, 1893. tMndel.)

To all whom tt may concern Be it known that I, ISAAC H. 00X, ofBridgeton, in the county of Cumberland, and in the State of New Jersey,have invented certain new and useful Improvements in (Jan SolderingMachines; 7 and I do hereby declare that the following is a full, clear,and exact description thereof, reference being bad to the accom pan yingdrawings, making a part of this specification, in which Figure l is aperspective view of my machine as arranged for use. Fig. 2 is alike viewof the same when in use. Fig. 3 is a verticalcentral view uponalinepassing lengthwise ot' the frame, and Fig. 4 is a vertical cen.-tral cross-section.

Letters of like name and kind refer to like parts in each of thefigures.

The design of my invention is to enable thecaps to be simultaneouslysoldered upon a number of cans; and to this end it consists in the meansemployed for rotating the solderingirons, substantially as and for thepurpose hereinafter shown and described.

It consists, further, in the means employed for moving thesoldering-irons toward or from the cans, substantially as and for thepurpose hereinafter specified.

It consists, further, in the means employer for heating the solderingirons,substantially as and for the purpose hereinaftershown.

It consists, further, in the means employed for cleaning and retinningthe soldering-irons, substantially as and for the purpose hereinaftershown and described.

It consists, finally, in the machine as a whole, its parts beingconstructed and combined to operate in-the manner and for the purposesubstantially as hereinafter specified.

In the annexed drawings, A represents a rectangular frame having ahorizontal bottom, a, andan open upper side, and supported at a suitableheight by means of legs B, which are preferably placed near or atthecorners of said frame, and have their lower ends secured in placeupon a floor.

Fitted loosely within the frame A is a plate, 0, which corresponds inhorizontal dimensions to the like features of the interior of the same,and at each end is provided with an arm, 0, that extends outward througha vertical slot, at, which is formed in the contiguous end of said frameand terminatesin a round boss, 0. Said boss is engaged by the concaveupper end of a bar, I), which at its lower end is jointed to one end ofa lever, E, that is pivoted to or upon the endof said frame, and has itsouter end connected by means of a pivoted bar, F, to or with thecorresponding end of a similar lever, E, located at the opposite end ofthe machine, the arrangement being such as to permit said levers to besimultaneously operated by said rod, so as to move said plate 0vertically within said frame A.

Journaled in two parallel lines within the plate 0, and extendingdownward through the bottom a of the frame A,.are a number ofsoldering-irons, which consist each of a cylinder, G, having at-itsupper enda .journal, 9, and above the same a toothed pinion, g, saidcylinder being below said plate and said pinion above the same.

Between the rows of pinionsg' is a rack-bar, H, which has its sideedges, 71, toothed to engage with said pinions, and is provided upon itsface with a central longitudinal line of teeth, It, that are engaged bya toothed segment, I, which is provided with a radial handle, t. Saidsegment is pivoted between two cars, 0 that are secured to the plate 0and extend upward therefrom through two longitudinal slots, h which areprovided in said rack-bar. As thus arranged, the oscillation of saidtoothed segment upon its pivotal hearing will cause said toothedrack-bar to be moved to and fro longitudinally, and said pinions, withthe soldering-irons G, to be partially or entirely rotated in oppositedirections. The

lower ends of the soldering-irons Gr have such shape as to enable eachto fit over the cap la of a cam, K, and, being heated and raisedsufficiently a number of cans corresponding to the number of saidsoldering -irons are supplied with caps and solderand arranged within.asuitable box, L, and placed beneath the frame A in such position as tobring each can directly beneath one of said soldering-irons, after whichthe latter are lowered until they rest upon said cans, and are thenrotated until said solder has become melted.-

In order that variation in the height of the cans K may not prevent theperfect operation of the soldering-irons G, the journal 9 of each of thelatter has such length as to permit of a considerable amount of verticalmotion within the plate 0, by which construction each soldering-iron isfree to move in such direction within the necessary limits withoutaffecting the movements or operation of the other soldering-irons.

Each cap it is held in place before the soldering-irons G are broughtinto operation, and afterward, whilethe solderis cooling, by means of arod, M, which passes loosely through an axial opening, 9 in each of saidsoldering irons, and at its upper end is provided with a weight, m. Saidrod has such length as to cause its lower end to project considerablybelow the lower end of its soldering-iron when the latter is raised fromcontact with a can.

In use said rods impinge upon said caps before ter the latter are raisedfrom contact with said end of each soldering-iron.

caps said rods maintain their contact and hold said caps in place whilethe solder is cooling.

The box L is preferably kept in lateral position by means of a. rail, N,which is secured to or upon the floor and over which said box slides,while its longitudinal position is insured by a stop, 0, that projectsfrom either said rail or floor and engages with the end of said box.

In order that the soldering-irons Gr may be easily cleaned and retinned,I provide for each a block, I, which corresponds in size and generalshape to the like features of the cans K, and at its upper end has arecess, 1), which is exactly the reverse of the shape of the lower Eachblock I has its recess 11 now supplied with acid and solder, and isplaced within the box or tray L, and the latter then moved to placebeneath said soldering-irons, after which the latter are lowered intocontact with saidblocks, and then rotated in the same manner as whencans are being capped, the result being the easy and perfect cleaningand retinning of said irons.

In order that the soldering-irons G may be heated to and maintained atthe necessary temperature, I provide for each pair a burner, Q, whichpasses through the frame A at a point midway between saidsoldering-irons, and is adapted to throw horizontally inward a flame.Immediately in front of said burner I place a /\-shaped deflector, (1,upon which the flame impinges and is divided, one-half being directedagainst each solderingiron. The amount of combustible materialpermittedto be consnmed'by said burner governs the temperature of saidsoldering-irons and enables each to be kept at the most efficient point.

Having thus fully set forth the nature "and merits of my invention, whatI claim as new is- 1. A can-soldering machine provided with two or moresoldering-irons journaled in a vertically-reciprocating plate, a'slidingrack on such plate gearing with pinions on theupper ends of the rotatingirons, and means for actuating the rack, substantially as and for thepurpose set forth.

2. In combination with the journaled solder ing-irons Gr, provided eachwith a pinion, g,

the rack-bar H, having toothed side edges which mesh with said pinions,and adapted to be reciprocated longitudinally by means of the pivotedtoothed segment I, substantially as and for the purpose shown anddescribed.

3. In a can-soldering machine, in combination with each pair of rotaryand reciprocating soldering-irons, the burner Q, projecting inwardthrough the side of the frame, and the deflector fixed on the bottomplate of the frame, between the soldering-irons, substantially as andfor the purpose described.

4. In combination with the plate 0, adapted to carry thejournaledsoldering-irons G, and

provided with the arms 0 and bosses c, the

hinged bars I), pivoted levers E, and bar F, substantially as and forthe purpose shown.

5. In combination with the soldering-irons G, the cleaning and tinningblocks P, having their'upper ends fitting over or upon the lower ends ofthe former, and contained within the box L, substantially as and for thepurpose shown and described.

6. In a can-soldering machine, the combination of the slide provided onboth sides with rack-teeth to engage the two rows of pinions on thesoldering-irons, the ears attached to the bearing-plate and extending upthrough slots in the slide, and the actuating mechanism journaled insaid cars, all so arranged that the ears act with the slots as guidesfor the slide, substantially as specified.

7. In a soldering-machine, the combination of the following elements, towit: the series ofsoldering-irons journaled vertically in avertically-movable plate, the rack sliding on and supported by theplate, and engaging the pinions attached to the soldering-irons,operating mechanism therefor, the weighted rods for holding the caps inplace, and means for holding the cans in position whilethey are beingoperated upon, all substantially as and for the purpose set forth. I

In testimony that I claim the foregoing I have hereunto set my hand this16th day of February, 1883.
